The support Hunter dudes are cannon fodder that can't seem to do any damage before getting picked off. I echo everything GorriDev said. Seems like you put a lot of work into this but I don't really understand a way to play where I can do anything meaningful beyond dying.
It's also super slow to gather troops at the base, then take them out to the world to fight (and quickly die), and then it's slow to go back to the base and re-amass them. Too much waiting.
150mb for a web build is also absurd, maybe it's the audio files taking up most of the space?
